The music market has completely changed in the past decade. Artists create, distribute and monetize their music digitally. One step, however, is still stuck in the past: promoting music is as inefficient as it always was. Groover has built a digital platform that allows artists to reach curators (e.g. a music blogger or radio station) that are most likely to be interested in their style. This helps artists to gain visibility and new fans. Curators are incentivized to respond and give critical feedback to the artist's songs. They receive a small payment for every answer. At the heart of Groover’s algorithms is a deep hybrid neural network to match each artist with the best curators for their music.
